Blur

Tailwind CSS version
v2.1+

Utilities for applying blur filters to an element.

Default class reference

Class
Properties
blur-none--tw-blur: blur(0);
blur-sm--tw-blur: blur(4px);
blur--tw-blur: blur(8px);
blur-md--tw-blur: blur(12px);
blur-lg--tw-blur: blur(16px);
blur-xl--tw-blur: blur(24px);
blur-2xl--tw-blur: blur(40px);
blur-3xl--tw-blur: blur(64px);

Usage

Use the blur-{amount?} utilities alongside the filter utility to blur an element.

<div class="filter blur-lg ...">
  <!-- ... -->
</div>

Responsive

To control an element’s blur at a specific breakpoint, add a {screen}: prefix to any existing blur utility. For example, use md:blur-lg to apply the blur-lg utility at only medium screen sizes and above.

<div class="filter blur-sm md:blur-lg ...">
  <!-- ... -->
</div>

Customizing

You can customize which blur utilities are generated using the blur key in the theme section of your tailwind.config.js file.

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       blur: {
+         xs: '2px',
+       }
+     }
    }
  }

Learn more about customizing the default theme in the theme customization documentation.

Variants

默认情况下, 针对 blur 功能类,只生成 responsive 变体。

您可以通过修改您的 tailwind.config.js 文件中的 variants 部分中的 blur 属性来控制为 blur 功能生成哪些变体。

例如,这个配置将生成 hover and focus 变体:

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       blur: ['hover', 'focus'],
      }
    }
  }

Disabling

如果您不打算在您的项目中使用 blur 功能,您可以通过在配置文件的 corePlugins 部分将 blur 属性设置为 false 来完全禁用它们:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     blur: false,
    }
  }
